Abstract

In the preparation of expandable styrene polymers by polymerizing styrene, if desired together with up to 50% by weight of other monomers, in aqueous suspension with addition of a C3- to C6-hydrocarbon as blowing agent and, if desired, conventional additives in effective amounts before, during or after the polymerization, foaming is reduced if the aqueous phase contains from 0.05 to 0.3% by weight of polyvinylpyrrolidone having a K value of from 100 to 150 as protective colloid.
